Hello gang,I'm having a problem identifying a rattling noise coming from my water pump area,it only happens after the engine is warm and I accelerate,and it doesn't stop until I stop pressing gas.

The technique I always used to identify where such a noise was coming from was to use a very long screwdriver (2 feet long), while the engine is running. CAREFULLY touch the screwdriver end to each pulley or other object under the hood, and put your ear to the handle. The device making the noise will become very clear.

It could be AC pump/clutch, alternator, water pump, power steering pump, etc.

when oil is cold it is thicker and stays [on]coats metal as oil warms up it thins out and flows better[makes it thinner will hear ticking] sounds like a bad lifter or even camshaft lobe problem ,could also have a problem with a loose or out of adjustment rocker arm

Sounds like bearing in water pump is bad.

sounds like the water pump has blown a seal and bearing and it is now time to replace it with a new one.

If it is a 'squealing' noise it's probably the alternator/power steering drive belt. Before you turn on the engine in the morning, lightlt smear or spray some oil on the inside of the drive belt to lubricate it. If the squealing stops/disappears, then that's the fault ..

That squealing noise can be caused by an incorrectly tensioned belt, or a worn belt. Replacement is the only option.

The other frightening sounds can best be described as 'rattles' or 'tapping'. When a car stands overnight all the oil drains back into the sump (oil/pan).

There are two things (usually) that can be cause the rattle/tap:
1. Because the oil hasn't been pumped around the system, at start up worn big end bearings can rattle and tap on the crankshaft until the oil 'fills the gaps'. The tapping/rattling goes away as the engine warms and oil is pumped around the lubricating system.

A 'bottom end tapping' is a symptom of worn big ends (they are bearings at the bottom of the piston and fit around the crankshaft).

2. A rattle/tapping from the top of the engine can either be a worn camshaft or 'lazy tappets'. Again, when the engine warms and oil gets to the camshaft and tappets (also called 'hydraulic lifters) the noise will disappear.

If your car has this rattling/tapping noise - identify whether it is coming from just under the rocker box (ie the camshaft/tappets..) or the bottom end of the engine (big end bearings).

If the noise is coming from the top of the engine, try an oil change with a can of thick 'additive' included. A lazy tappet (lifter) isn't too much to worry about. A worn camshaft will affect the performance of the engine, though continue to do its job. An oil change with an additive included may help in quitening things down.

A bottom end tap/rattle (or 'knock') - the sooner that is sorted out the better.

lots of parts, alternator, water pump, a/c compressor lower area . many of them are on the serpentine belt. the pulleys and tensioner can make rattles. you need to confirm which part has the rattle or vibration, use a stick or screw driver. touch one end on the part and the other near your temple...any noise/vibration coming through?

fiind which one it is. lower noise on the crank can also sound like its coming from up front and that's a deep rattle.

sounds like your catalatic convertor,lifters?

Hello there Its a Known problem with these engines..The lifters are usually the case to thes problem or the rocker arms are coming loose.Take off valve cover and start to find the bad one..Oil will leak over head but is the only way to pin point the problem.If the sound is a little lower in the motor It might have a sloppy rist pin in the cylinder causing the piston to slap the side walls..If it does it at an idle or under a load its the rist pin.If it does it at all different rpm and doesnt matter if its under load its the lifter area.Now the timing chain.Could case all thee above.So a way to check that is as long as you got the belt off grab a hold off the crank pulley and rock it back and forth.If you feel it grab a few inches side to side iits really loose and thats your problem.If it doesnt have much slop back and forth and turns the cam quickly the move on to the other parts I have stated.These steps will help you to solve the problem.I hope this helps you and good luck..Have a great after noon...

water pump by teh sound of it seal ok but bearing going

Look for water pump, fan belts, steering belt, AC belts and pulleys. These are common causes of these strange noises which come on and off. Also check all the mechanical nuts, bolts, screws are tightened and not rattled.
